SPECIPICATION forming part of Letters Patent No. 364,100, dated May 31,1887.

Application filed March 14, 1887; Serial No. 230,899.

- and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

Our invention relates to steam and water boilers, and provides means forallowing. the boiler to be reversed, thereby giving to the latter alonger life.

By the peculiar construction of the furnace and of the boiler a greatgain is experienced not only in the first cost but in the continued use.To this end we construct our boiler so as to allow of its beingreversedthat .is to say, when by prolonged use the head nearest the firebecomes worn, the boiler is turned over and the head that was farthestaway is presented to theaction of the fire.

In the accompanying drawings, Figure 1 is a vertical sectional view ofthe whole invention. Fig. 2 is a horizontal section of the boiler; Fig.3, a front view of furnace and boiler-shell; Fig. 4, the outside view ofboiler proper; Fig. 5, the base-plate on which rests the boiler. Fig. 6is the top plate placed over the boiler.

Similar letters of reference indicate like parts in all the figures.

The salient point in my invention is the construction of the boiler andfirebox permitting the reversing of the former. The form of thefire-box'A is circular, and it is so constructed as to be adapted tosecurely sustain the base- 'plate 13, which in turn receives the boileras it is set upon it, the annular projection (I don d d represent anannular proj ec- (No model.)

the head of the boiler preventing displacement. The outer casing, I, isfitted around the boiler and on the base-plate, the top plate, M, putover both, and the pipe-connections made up.

It is ofimportance to note the position of the doors at the level of thegrate-bars and of the floor of the ash-hole, this construction affordinggreat convenience and speed in the removal of clinkers and ashes.

The heat rises up through the flues D D, and, collecting in H, travelsdown the fl'ues E to the base-plate, up through the heat-space betweenshell and outer casing, and out through the draft-flue J. The tube Mallows of the fire being fed from the top. When the boiler has been usedfor a certain time in this position,

it will be readily seen that it can be reversed, so that the head thatwas next to the fire is now found to be uppermost, and the one that hadnot been acted upon by the fire is in a bet- 'ter condition than theother, and therefore will practically double the life of the boiler. I

It will be noted that both heads of the boiler are meant to-be similarin construction, so as to present no difficulty in reversing it, and theprocess of doing so is simplicity itself, only requiring that the topplate, H, be removed and the pipes be disconnected, the casing I takenoff, the boiler-reversed, and the casing and-col- We are aware thatprior-to our invention a boiler capable of being removed from the outercasing has been constructed, and also afurnace having doors oua levelwith the floor of the ash-pit, and we do not claim these, broadly; butthe construction of our boiler and the different parts of thesupporting-furnace are,

we believe, novel. a

Havingnow described our said invention,

what we claim as new, and desire to secure by Letters Patent, is-

1. The combination of a reversible tubular each head, of aboiler-furnace provided with door-openings formed on a level with thegratebars and with the ash-floor, a base-plate constructed to form acommunicating channel between the lateral fire-flues and surroundingair-space, a removable top plate, and a fuelchute, substantially asdescribed.

In testimony whereof we affix our signatures in presence of twowitnesses.
